BOX for eclipse subs

Need to build a box for 2 SW8200's (eclipse). theyre 12"s. thing is he wants them in a ported box and i cant find info anywhere on the size or tuning of a box for them. everywhere says sealed. but he wants ported so any suggestions?

sorry man but ford will always be a ford. ford is the sony xplod of cars and trucks. you had bad experiences with chevy because your a ford guy. its what seperates the men from the boys. friend billy use to drive a ford. he drives a chevy now. they call him billy no more. hes known as bill now..
